run.sh script using IBM java cannot detect 64bit version

When using IBM JDK and starting EAP with jboss natives unpacked on proper place run.sh doesn't detect 64bit version of jvm correctly.
In fact it sets it to 32bit all the time.

In run.sh there is a grep command used to detect binary version and IBM JDK's java -version output doesn't contain "64-bit" string, rather "amd64-64".

Maybe we can use:
IS_64_BIT_JVM=`"$JAVA" $JVM_OPTVERSION 2>&1 | $GREP -i -e 64-bit -e amd64-64`
instead of original.
